Having an issue where clients connecting to A radios on an 1142 drop off every 2 and a half minutes. Running off a WLC 4402 running code 126.96.36.199. Issue cannot be replicated on an 1131 or 1242 running A radios. Opened a TAC case but interested to know if this is a problem seen elsewhere.
OK, finally found this one in the Bug list. Bug CSCsw20879 covers exactly what we were seeing. Weird we were only getting it on the 1142AP's and not the 1131 or 1242 AP's. Either way, the fix of updating the channel scan under RRM->General on the a radios to be 'country channels' and not 'all channels' appears to have fixed the issue.
